Gateway API Updates
1.0 was released a couple months ago. 1.1 will contain some QoL improvements. Overview of GEPs can be found here.
Mutual TLS is being worked on, but the maintainers are stuck on naming things.
Conformance Profiles
The problem is that it's hard to track implementations because there's no tracking mechanism to begin with. Feedback is really important, so Conformance Profiles were introduced.
Each part of the API has extensive test coverage and all implementations are meant to pass all tests in the suite. A profile is like a group of test suites.
